Abstract
The present disclosure provides for cooling systems, assemblies and methods (e.g., for semiconductor devices; for refrigerant cooling; for cryogenic cooling). More particularly, the present disclosure provides for mini-channel cold plate cooling assemblies, systems and methods for semiconductor devices (e.g., wide-bandgap (WBG) power semiconductor devices), with the cooling assemblies, systems and methods utilizing three-dimensional adaptive flow-paths using bi-metal fins. The present disclosure provides for mini-channel cold plate cooling assemblies, systems and methods that may improve cooling performance and/or enable local cooling control. The present disclosure provides for bi-metal strips that operate as both the surface-temperature sensors and actuators without input energy. The bi-metal strips guide the coolant flow to a low-drag channel when the surface temperature is low, and guide the coolant flow to the near-surface channel when the surface temperature is high.
